4-[1-Oxo-3-(substituted aryl)-2-propenyl]-3-substituted phenyl sydnones (2a-i, 3a-i, 4a-i) are synthesized by ultrasonication method. The synthesis was carried out by reaction of 4-acetyl-3- (substituted phenyl)sydnones (1a-i) with various substituted aryl aldehydes (Ar-CHO). The structures of compounds were established by using NMR, IR, MS and elemental analysis. Compounds were evaluated for antibacterial, antifungal and antioxidant activity. Some of the synthesized compounds have shown good to moderate activity against gram negative bacteria whereas compounds 3c, 4c and 4f have shown marked activity against fungal strains. The compounds 2c, 3c, 4f have shown potent antioxidant activity as compared to reference standards. The compound 4f (IC50 = 3.17 μM) is the most potent with methyl group as substituent showing good antioxidant activity even at very low concentrations. The ultrasonic method of synthesis was found to be simple, reduces reaction time and gives good yield when compared with traditional methods of synthesis.
采用超声法合成了 4-[1-氧代-3-(取代的芳基)-2-丙烯基]-3-取代苯基茚酮 (2a-i、3a-i、4a-i)。合成是通过 4-乙酰基-3-(取代苯基)茚酮(1a-i)与各种取代芳基醛(Ar-CHO)反应进行的。化合物的结构是通过核磁共振、红外光谱、质谱和元素分析确定的。评估了化合物的抗菌、抗真菌和抗氧化活性。一些合成化合物对革兰氏阴性菌具有良好至中等程度的活性,而化合物 3c、4c 和 4f 则对真菌菌株具有明显的活性。与参考标准相比,化合物 2c、3c 和 4f 具有很强的抗氧化活性。以甲基为取代基的化合物 4f(IC50 = 3.17 μM)的抗氧化活性最强,即使在很低的浓度下也能显示出良好的抗氧化活性。与传统的合成方法相比,超声波合成法简单、反应时间短、产量高。
